The German premium car maker agreed with the Japanese
manufacturer last December to supply diesel engines to Toyota
from 2014 in Europe and collaborate on lithium-ion battery
research for electric cars.

Both companies have since been exploring other fields for
cooperation and have now agreed several projects, Der Spiegel
said without being more specific. BMW Chief Executive Norbert
Reithofer and Toyota President Akio Toyoda will announce details
in the near future, the magazine said.

A spokesman for Munich-based BMW declined to comment on the
report.

Last week, BMW's joint venture to make hybrid car components
with French auto maker PSA Peugeot Citroen was thrown
into doubt by the prospect of deepening ties between PSA and its
European rival Opel, a division of General Motors.
